Warwickshire’s population projected to increase to 623,900 people by 2037

The primary purpose of the subnational projections is to provide an estimate of the future size and age structure of the population of local authorities in England. The latest 2012-based projections released by the ONS yesterday suggest Warwickshire is projected to be home to 623,900 people by 2037.  This is a 13.9% increase or 75,900 people in the 25 year period, lower than the equivalent national increase of 16.2%.

How a population is projected to change locally depends on a number of factors that can interact and produce very different growth rates to England as a whole. The size and age structure of the population at mid-2012 is a big indicator of the future population.

Warwickshire’s population as a whole is projected to be more heavily influenced by migration than natural change (births-deaths) into the future and particularly in later years of the projection, internal migration (between local authorities) plays a larger role in influencing the figures.

Some local planning needs are directly relevant to specific age groups and therefore it is important to understand the possible changes to the age structure of an area when planning for the future.

Overall Warwickshire is expected to grow by 13.9% over the 25 year period, however, this mask considerable variation when looking at broad age bands.  The population aged between 0-15 years is expected to grow by 7% in the 25 year period while those aged between 16-64 years is looking at a fall of 0.2%.  Those aged 65 years or over are expected to increase by nearly two thirds (64%) over 25 years and when we consider the population aged 90 years or over, this rises significantly to 269% (over 2 and a half times the current number of 90+ year olds).

Interactive population pyramidsThe ONS projections released yesterday are considerably lower than the previous 2010 and 2011-based projections across the county. This is likely to be due to the fact that the trends used in the 2012-based subnational population projections are based on a historical population series rebased following the 2011 Census while the trends used in the 2011- based subnational population projections are based on an older population series that does not reflect the findings of the 2011 Census. Other reasons include:

  • changes in the population estimate, used as the base year in the projections, between mid-2011 and mid-2012,
  • changes in the trends (births, deaths and migration),
  • changes in assumptions for international migration at a national level

The team will be looking at these estimates in more detail over the coming weeks, however, ONS have produced an interactive tool to look at how the population is changing over time in your area.
